Universal Netlist MCP Server

The Universal Netlist MCP Server gives AI agents the tools to understand and analyze your electrical schematics, for powerful and comprehensive design reviews through natural conversations.

It is compatible with Cadence and Altium, with plans to integrate more EDAs in the future. Note that you must already own a license of these EDAs to unleash the full capabilities of this MCP server.

Supported Formats

| Format | Input Files | Description | |--------|------------|-------------| | Cadence (CIS / HDL) | .dat netlist files | Exported Allegro netlist files (pstxnet.dat, pstxprt.dat, pstchip.dat) from Cadence Capture CIS or HDL designs | | Altium Designer | .SchDoc | Altium schematic documents (discovered via .PrjPcb project files) |

Native Install (Recommended)

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/IntelligentElectron/universal-netlist/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/IntelligentElectron/universal-netlist/main/install.ps1 | iex

Why use the native installer:

• No dependencies — standalone binary, no Node.js required
• Auto-updates — checks for updates on startup
• Signed binaries — macOS binaries are notarized by Apple

The installer downloads two files:

1. Binary - For CLI usage and manual MCP client configuration
2. Claude Desktop extension (.mcpb) - For easy Claude Desktop integration

| Platform | Install Directory | |----------|-------------------| | macOS | ~/Library/Application Support/universal-netlist/ | | Linux | ~/.local/share/universal-netlist/ | | Windows | %LOCALAPPDATA%\universal-netlist\ |

Update

The server checks for updates on startup. To update manually:
